Hi, I often travel from Z2 to Z4 via Z1. Can I buy a Z234 travelcard,
or do I need a Z1234? I assume that it might be fare evasion if I use
it, but will it let me through the gates?

A paper Travelcard will, but an Oyster card will count the journey as
via Z1 and charge you an excess (usually - if there's a sensible route
not via Z1 it may assume you've gone that way).
But then, I can't buy a 7 day paper travelcard, can I?

Yes you can - at a National Rail station that is not equipped for Oyster
tickets and there are literally hundreds of those.

Besides, how
does the system know which route is sensible?

Someone has defined that in the commercial rules. All systems like this
have to have them or else anarchy rules. Under the pre Oyster system
certain single tickets on LU had implied routeing in order to derive the
fare. We still have issues today for certain journeys like Stratford -
Richmond or Highbury - Richmond where there are three rail route options
and 3 or 4 different fares.

I know that in some
cases it is impossibe to travel between certain stations without
touching Z1, but sometimes you can indeed do it by using another,
longer route. The system doesn't know which route you travel, so does
it assume the shortest one or just looks at the zones you enter or
exit?

The system will apply the commercial rules it has been given.

You *seem* to be asking for permission to travel via Zone 1 but not pay
for it. Either pay the money up front for a Travelcard including Z1, or
get charged via PAYG on Oyster, or travel not via Z1 or else cheat the
system and run the risk of being caught for fare evasion and face
potential prosecution.

If I was to guess how you made your journeys I would say District Line
direct or else District and Central Lines. Am I right or am I right?

Admits to working for London Underground!

Yes I am using mostly Central and District lines, DLR sometimes. And
basically, you are right that I am trying to go through Z1 without
paying for it, and I agree that it is not right thing to do. But then,
what are the chances of being caught? Do they even check the tickets
in the Underground (I know they do in DLR, but then it's within Z23)?

If you can buy a paper travelcard, what is the advantage of using
Oyster then? They cost the same, don't they? So what's the difference?
By the way, can you buy it in the DLR ticket machine?
